POST OR POLE.

Specification of Letters Patent.

Patented June 29, 1909.

Application led June 29, 1908. Serial No. 440,889.

l accompanying drawings, forming part of this specification.

My invention relates to that character of posts or poles in which concrete is employed asthe body or core of .resisting material and .it has for its object the provision of means within theconcrete body whereby said concrete body is reinforced or stitfened, and also the provision of means by which the concrete body is kept in place and restrained -fiom endwise movement in its casing, either during shipment of the posts or poles or after they are placed in upright positions for service, ibut more particularly during shipments. V

Figure I isa vertical or longitudinal section taken through a post or pole constructedv in accordance with my invention. Fig. II is acrbss section taken online II-II, Fig. I. Fig. III is a *View partly in elevation, and partly in longitudinal section of a modification.l t

In the accompanying drawings: l designatesy the lower section, having a flared hollow base l', and 1 the reduced upper section, having a cap 1, of the casing of my post or pole, and 2 is the concrete body or core molded within said casing. This concrete body or core is reinforced and strengthcned by a stiflener rod 3 that extends longitudinally through the center of the body or core to serve as a brace member to lessen the liability ot breakage of the concrete body or to take the entire strain that may be imposed upon the post or pole in the event of the concretebody becoming fractured at any one or more points.

For the` purpose otl preventing endwise :movement of the concrete body and also of the stiffener rod within the post or pole when the base lofthe casing is made of open `form, I mount in said casing at or nearY the lower end of the concrete body `a rivet er bolt 4, againstwhich the lower end of the stiffener rod impinges, and whiclrby extending transversely of the concrete body efficiently performs bthe service it is intended to perform. The lower section l and the upper section l of the post or pole illustrated in Fig. I are united by an intermediate bolt or rivet i passing through the stifl'ener rod and when the casing is so made,

this intermediate bolt or rivet 4:.by passing y through the concrete body also serves in conjunction with the lower bolter rivet 4 to hold the concrete body from movement within the easing surrounding it. 'l is an upper rivet -or bolt passing through the cap 1 and through the upper end of the concrete body and securing the cap and preventing the outward movement of the stiffener rod 4 a rivet or bolt securing the cap and preventing the upward movement of the stiffencr rod 3% l, The casing of this post or ole is Ymade tapering at its base to provide tor the retention of the concrete body within the casing thereby dispensing with theneeessity for the use et a bolt or rivet mounted in the casing as hereinbefore described.

Having thus described my invention the following is what I claim as new therein and desire to secure by Letters Patent:

A post or pole comprising a` easing constructed vfith'a lower section having a flared hollow base and an upper reduced section having a cap,a lower rivet or bolt passed through thelower section at the upper end of the fiared hollow base, an upper rivet or bolt'passed through the cap and the upper end ,of the upper section, a concrete body or core within' the lower and upper sections of the casing, a stitfener rod embedded within said concrete body or core and extending longitudinally thereot1 and having its ends impingiug against the lower and upper rivets or bolts respectively, and an intermediate rivet or bolt passed-through the adjacent ends of the lower andv upper sections of the casing and through the stiff'ener rod.
